|ClinicalTrials.gov Identifier: NCT01361607|
Recruitment Status : Completed
First Posted : May 27, 2011
Last Update Posted : July 6, 2016
This 9-week study aimed to determine the efficacy, safety and tolerability of Sativex® (Nabiximols) as an adjunctive treatment, compared with placebo in relieving uncontrolled persistent chronic pain in patients with advanced cancer.
Eligible patients were not required to stop any of their current treatments or medications.

This 9-week, multi-center, double-blind, randomized, placebo-controlled study aimed to determine the efficacy, safety and tolerability of Sativex administered as an adjunctive treatment for 5 weeks, vs. placebo. Eligible patients had advanced cancer, with a clinical diagnosis of cancer related pain which was not wholly alleviated by their current optimized opioid treatment.
Qualifying patients entered the study at Visit 1 and commenced a 5-14 day eligibility period. During this period, eligible patients had 3 consecutive days where pain severity remained within defined parameters, break-through opioid usage had not exceeded an average of 4 episodes per day, and maintenance opioid medication and dose had not changed. Eligible patients returned for a randomization visit (Visit 2, Day 1) and were randomized to either Sativex or placebo using a 1:1 allocation ratio. Patients began an initial titration period lasting up to 14 days; the titration schedule required dosing to a minimum of 3 sprays per day, after which patients were allowed to individualize their dose (3-10 sprays per day) by Day 14, and that dose was then fixed for the remainder of the study. Patients returned at Visit 3 (Day 22) and Visit 4 (Day 36, end of the randomized treatment period), or earlier if they terminated prematurely from the study. After the end of the 5-week treatment period, patients were offered the option of entering an open-label extension (OLE) study; a safety follow up visit (Visit 5) was not required if the patient entered the OLE on the same day as Visit 4. Patients who entered the OLE up to 7 days after Visit 4 had their Visit 5 assessments performed on the same day as their first OLE study visit. Patients that did not enter the OLE study had a safety follow up visit (Visit 5) 14 days after treatment completion, which could be via telephone.
